Visual Datasets
The Visual Datasets text module discusses the concept of visual learning and presents some suggestions for ways to design learning environments that support students in developing visual literacy skills. Three visual datasets that can be used for problem solving activities in evolution, classification, development, and botany are included:
Caminacules: A dataset of imaginary animals that can be used as the basis for a variety of problem-posing and problem-solving activities in evolution, classi
SimBio2
From 1991 until 1993 the Biosphere system supported people, plants, and animals. Experiments offered the opportunity for tracking in great detail the interactions among land and water ecosystems and the atmosphere.
SimBio2 offers several scenarios in which students can generate simulation graphs using actual data from the Biosphere 2 experiment. Studentscan explore some of the problems that affected Biosphere 2 such as higher levels of carbon dioxide than expected and the resulting decrease oxy
Resistan
Resistan is a mechanistic simulation model of the process of selection of fungicide-resistant biotypes of a hypothetical fungal pathogen of a hypothetical crop.
The fungus is a polycyclic organism with many generations per season. There is no genetic component in this simulator. Reproduction is assumed to be asexual. A small proportion of the initial inoculum is designated as the fungicide-resistant biotype at the start of the season, and the response of that population to various fungicide spr
Environmental Decision Making
Using the Extend 'connect-the-components' visual programming, students can model and simulate ecosystems including social and economic forces as well as study parameter variations to develop an understanding of ecosystem function and productivity.
By making 'what if...' changes in the model, the effects of various proposed decisions about the environment can then be shown.
EDM includes three ecological systems: Ponds, Grasslands, and Logging. Students can predict results of changes in the mode
CuraÁao
CuraÁao is a computer program that simulates the sterile insect release method (SIRM) of pest population suppression, first conceived by E. F. Knipling (1955).
The user can investigate the effects of several variables on the effectiveness of the method and discover what happens when some of the basic assumptions of the model are relaxed or violated in some way. The user should gain some understanding of the sorts of things that complicate the application of the technique in situations that are
Cell Differentials
Cell Differentials offers a visual dataset of white blood cells that gives students practice in developing strategies and techniques for the recognition of these blood cell types.
Over 100 different cell images are randomly presented with feedback on successful identification.
In traditional labs, the recognition of white blood cell types can be compromised by several factors. Developmental changes can make recognition difficult and some cell types exhibit similar features. Microscopy can be a
Environmental Explorers' Club
This is a place where kids can learn about the environment and the Environmental Protection Agency. It features plants and animals, air, water, people and the environment, recycling, and a clubhouse area containing art, a game room, a science room, and a trophy room listing the winners of the President's Environmental Youth Award.

Scaffolding: A model for learner support in an online teaching environment
'In the design of online teaching environments, considerable attention has been paid to the nature of the interface and to the streamlining of activities for learners to engage with. Much less attention has been given however to the nature of the learner support system that is created for novice users learning online. Support systems are essential for learners to engage in the processes of learning and need to be developed in response to needs. It is also imperative that a range of support syste
5.1 A second major discovery In the introduction to this course, we said that there were three pillars of evidence for the big bang. We now turn to the second. It rests on a discovery that ranks in importance with that of Hubble's law. It came about when observations in a new region of the electromagnetic spectrum – the microwave region – became possible. This was due to the invention of new detectors, working at frequencies as high as 30 000 MHz. In 1965, two Bell Telephone scientists, A. Penzias and R. Wilson, were

Reflections on Playing Ayiti: The Cost of Life
Ayiti: The Cost of Life is a role-playing video game in which the player assumes the roles of family members living in rural Haiti. At the start of the game, the player chooses a primary goal for his/her family: achieve education, make money, stay healthy, or maintain happiness. During the course of the game, the player encounters unexpected events and must make decisions that contribute to or detract from achieving the chosen goal. After students have played the game they will need to reflect u

Disaster
The people who came to California in search of gold were faced with the threat of disaster in every step of their journey. Many came by ship, even though shipwrecks were commonplace ? one set of lithographs depicts four shipwrecks that occurred within 60 days. Earthquakes were another fact of life in California. Sensational newspaper illustrations like "Earth Quakey Times," and photographs showing buildings in shambles, helped build the state's reputation as an "earthquake capital." Earthquakes
3.2 Migrations of life As biologist and pioneer environmentalist Rachel Carson once wrote: ‘the stocking of the islands has been accomplished by the strangest migration in earth's history – a migration that began long before man appeared on earth and is still continuing’ (Carson, 1953, p. 66). Austronesian voyagers may have been the first people to venture far into open water, but many other species, as Carson suggests, have also found ways of negotiating passages across the ocean. Arriving at pockets of land
Medicine Games: Incredible Megacell Game
Play a game and find out about a Nobel Prize awarded discovery or work! The compartments of the cell, the organelles, are so small that it was impossible to study their structure until the electron microscope became available in 1938. Albert Claude, Christian de Duve and George E. Palade were awarded the Nobel Prize in Physiology or Medicine in 1974 for developing methods making it possible to take a closer look at the organelles and for discovering some of them.
4.3 Metallic bonding Two familiar properties of metals point to a simple model of metallic bonding. Firstly, metals have a strong tendency to form positive ions. Thus, when sodium reacts with water, and when magnesium and aluminium react with acids, hydrogen gas is evolved and the ions Na+(aq), Mg2+(aq) and Al3+(aq), respectively, are formed. Secondly, metals are good conductors of electricity: when a voltage difference is applied
Natural Inquirer Journals: Wildland Fire
This edition of the Natural Inquirer is all about wildland fire. You will learn about the benefits of wildland fire, as well as some of its dangers. You will learn what fire scientists are learning about wildland fire. They are learning, for example, 1) that wildland fire should not be completely eliminated from natural environments, but it should be managed; 2) how to predict which weather conditions most favor a wildfire being started; 3) about the relationship between wildland fires and globa
Essential Science for Teachers: Life Science: Session 4. Plant Life Cycles
What is a plant? One distinguishing feature of members of the Plant Kingdom is their life cycle. In this session, flowering plants serve as examples for studying the plant life cycle by considering the roles of seeds, flowers, and fruits. A comparison to animal life cycles reveals some surprising similarities and intriguing differences.,Seeds and their plants are similar to eggs and animals.
Privacy
Though it brings us many benefits, the march of technology makes an encompassing surveillance network seem almost inevitable, and radically changes our expectations of privacy. We owe many of the expectations of privacy we used to enjoy to a combination of immature technology and insufficient manpower to monitor us. But these protective inefficiencies are giving way to technologies of data processing and digital surveillance that will change our beliefs about privacy. We are widely tracked by pu
